Hi Karban,
The “Proper Network Activation” plugin resolved the problem. Thanks for the pointer.
For any future readers, I did the following:
- Removed the “Broken Link Checker” plugin from all sites
- Installed the “Proper Network Activation” plugin via the root site Dashboard and activated “PNA”
- Installed the “Broken Link Checker” plugin via the root site Dashboard and activated “BLC”
After these steps I verified that the BLC settings are available in each of the Sites in my network and verified that the checking returns results into the Dashboard for each Site.
This is the same issue that was happening with wordpress 3.2 when using wp-recaptcha with multi-site enabled. In the 3.1.3 version of wp-recaptcha there was a code patch that would fix the issue. In the 3.1.4 version of wp-recaptcha the code has been significantly changed making the previous patch irrelevant.
